Treatability Study in Support of Intrinsic Remediation for IRP Site 55- 16. Volume 1 - Report at Langley Air Force Base Hampton, Virginia

摘要

This report was prepared by Parsons Engineering Science, Inc. (Parsons ES) and presents the results of a treatability study (TS) conducted to evaluate the use of intrinsic remediation for remediation of fuel-hydrocarbon- contaminated groundwater at Installation Restoration Program (IRP) Site S 5-16 (a former military gasoline service station site) at Langley Air Force Base (AFB, the Base), in Hampton, Virginia. Previous investigations determined that fuel hydrocarbons had been released into the soil and shallow groundwater at the site. The main emphasis of the work described herein was to evaluate if naturally occurring attenuation mechanisms would be sufficient to reduce dissolved fuel-related compounds in groundwater to levels that meet state- specified groundwater protection standards. This study is not intended to be a contamination assessment report or a remedial action plan; rather, it is provided for the use of the Base and its prime environmental contractor(s) as information to be used for future decision making regarding this site.
